WAC 296-843-11005
Complete a preliminary site evaluation before allowing employees to enter the site

You must

  • Complete a preliminary site evaluation by doing all the following:
Collect or develop the following information to the extent available:
    • The site location and approximate size
    • A description of the response activity and the job tasks to be performed
    • The time needed to cover all planned activities
    • The site's topography and all ways to access the site
    • The current status and capabilities of any emergency response team assisting during an emergency
    • The safety and health hazards expected at the site
    • The hazardous substances and health hazards at the site, including their chemical and physical properties
    • All hazardous substance dispersion pathways
    • An emergency response plan
Have a qualified person evaluate the preliminary site information to identify:
    • Potential site hazards and risks
    • The most appropriate methods to protect employees
    • Conditions that have the potential to cause death or serious harm, including potential inhalation or skin absorption hazards that are immediately dangerous to life or health (IDLH)

      - Examples include:

              • Confined space entry
              • Potentially explosive or flammable environments
              • Visible vapor clouds
              • Areas where plants or animals have died
    • Risks related to specific on-site hazardous substances and health hazards

      - Examples include:

        • Exposures exceeding the permissible exposure limits (PELs) or published exposure levels
        • IDLH concentrations
        • Potential skin absorption and irritation sources
        • Potential eye irritation sources
        • Explosion sensitivity and flammability ranges
        • Oxygen deficient atmospher
Have a qualified person prepare an initial site characterization and analysis for the site to:
    • Identify known and suspected health and safety hazards for the site
    • Aid in selecting control methods to protect employees from site hazards
    • Brief employees on site conditions before any work starts
    • Initiate the site-specific health and safety plan (HASP)

Note

Characterization and analysis of site hazards is an ongoing process for work on the hazardous waste site.

WAC 296-843-11010

You must

(1) Have a qualified person complete further evaluation of health and safety hazards at the site immediately after initial entry to:

    • Identify site hazards in more detail.
    • Help select appropriate:
      • – Control methods to protect employees from site hazards.
      • – Personal protective equipment (PPE) for site operations.

Note
